Pages with colon on its title breaks Excerp Include macro on page copy

The problem

Copying a page that contains an Excerpt Macro that fetches data from pages with ":" on its name, breaks the macro.

Steps to reproduce

1. Create a new page with a name that contains ':' ie. "This is the page: Test"
2. Now, insert a Excerpt Macro, and type something in it
3. Create a new page, in the same level as the one above
4. Insert a Excerpt Include Macro on the page, and put the following parameters:

   SPACEKEY:This is the page: Test

5. Publish the page
6. Now, copy the page and publish it

Expected Behavior

The copied page will be published and the Excerpt Include Macro will display its content

Actual Behavior

The macro strips out the SPACEKEY from its parameters, so it interprets the first part of the "This is the page: Test" page as the Space, breaking the macro and displaying: Error rendering macro 'excerpt-include': No link could be created for 'This is the page'.
